A new framework called MAPLE has been developed for generating diverse and efficient multi-alpha signals in stock market portfolio construction. This method, detailed in a recent arXiv paper, uses a unified prediction head and a specialized ranking loss to explicitly control the correlation between different trading signals. MAPLE has demonstrated superior performance in Sharpe and Calmar ratios across multiple international markets compared to existing baselines, while requiring significantly fewer parameters and less training time.
